lol your method of asking for help is pretty weird Arbiter, like everyone else, told you 40 is pretty normal for your clock. He added 50+ is achievable, "with a serious overclock." No need to be insulting ><
Solution was already given. Overclock your CPU some more. You're doing a 4 ghz OC, which is probably the auto overclock. Taking it up to 4.2 (easily achievable with your i5) will bump your FPS a bit. Perhaps you'll start seeing 50+. Can go up to 4.4/4.5 depending on your cooling. Google "CPU simple overclock" for very easy OC steps.
